BACKGROUND OF THE INVENTION

The search for new therapeutic agents has been greatly aided in recentyears by a better understanding of the structure of enzymes and otherbiomolecules associated with diseases. One important class of enzymesthat has been the subject of extensive study is protein kinases.

Protein kinases constitute a large family of structurally relatedenzymes that are responsible for the control of a variety of signaltransduction processes within the cell. Protein kinases are thought tohave evolved from a common ancestral gene due to the conservation oftheir structure and catalytic function. Almost all kinases contain asimilar 250-300 amino acid catalytic domain. The kinases may becategorized into families by the substrates they phosphorylate (e.g.,protein-tyrosine, protein-serine/threonine, lipids, etc.).

Mitogen-activiated protein kinase-activated protein kinase 2 (MAPKAP K2or MK2) mediates multiple p38 MAPK-dependent cellular responses. MK2 isan important intracellular regulator of the production of cytokines,such as tumor necrosis factor alpha (TNF-α), interleukin 6 (IL-6) andinterferon gamma (IFNγ), that are involved in many acute and chronicinflammatory diseases, e.g. rheumatoid arthritis and inflammatory boweldisease. MK2 resides in the nucleus of non-stimulated cells and uponstimulation, it translocates to the cytoplasm and phosphorylates andactivates tuberin and HSP27. MK2 is also implicated in heart failure,brain ischemic injury, the regulation of stress resistance and theproduction of TNF-α. (see Deak et al., EMBO. 17:4426-4441 (1998); Shi etal., Biol. Chem. 383:1519-1536 (2002); Staklatvala., Curr. Opin.Pharmacol. 4:372-377 (2004), and Shiroto et al., J. Mol. Cardiol.38:93-97 (2005)).

Many diseases are associated with abnormal cellular responses triggeredby protein kinase-mediated events as described above. These diseasesinclude, but are not limited to, autoimmune diseases, inflammatorydiseases, bone diseases, metabolic diseases, neurological andneurodegenerative diseases, cancer, cardiovascular diseases, allergiesand asthma, Alzheimer's disease, and hormone-related diseases.Accordingly, there remains a need to find protein kinase inhibitorsuseful as therapeutic agents.

Examples of such purposes include,but are not limited to, blood transfusion, organ transplantation,biological specimen storage, and biological assays.

As used herein, a “disease or disorder associated with MK2” or,alternatively, “an MK2-mediated disease or disorder” means any diseaseor other deleterious condition in which MK2, or a mutant thereof, isknown or suspected to play a role.

The term “subject”, as used herein, means a mammal and includes humanand animal subjects, such as domestic animals (e.g., horses, dogs, cats,etc.). The terms “subject” and “patient” are used interchangeably. Insome embodiments, the “patient” or “subject” means an animal, preferablya mammal, and most preferably a human.

The term “pharmaceutically acceptable carrier, adjuvant, or vehicle”refers to a non-toxic carrier, adjuvant, or vehicle that does notdestroy the pharmacological activity of the compound with which it isformulated. Pharmaceutically acceptable carriers, adjuvants or vehiclesthat may be used in the compositions of this invention include, but arenot limited to, ion exchangers, alumina, aluminum stearate, lecithin,serum proteins, such as human serum albumin, buffer substances such asphosphates, glycine, sorbic acid, potassium sorbate, partial glyceridemixtures of saturated vegetable fatty acids, water, salts orelectrolytes, such as protamine sulfate, disodium hydrogen phosphate,potassium hydrogen phosphate, sodium chloride, zinc salts, colloidalsilica, magnesium trisilicate, polyvinyl pyrrolidone, cellulose-basedsubstances, polyethylene glycol, sodium carboxymethylcellulose,polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers,polyethylene glycol and wool fat. The amount of compounds of the presentinvention that may be combined with the carrier materials to produce acomposition in a single dosage form will vary depending upon the hosttreated, the particular mode of administration, etc. Preferably,provided compositions are formulated so that a dosage of between 0.01 toabout 100 mg/kg, or about 0.1 mg/kg to about 50 mg/kg, and preferablyfrom about 1 mg/kg to about 25 mg/kg, of subject body weight/day of theinhibitor can be administered to a patient receiving these compositionsto obtain the desired therapeutic effect. The amount of a compound ofthe present invention in the composition will also depend upon theparticular compound in the composition.

The expression “unit dosage form” as used herein refers to a physicallydiscrete unit of a provided compound and/or compositions thereofappropriate for the subject to be treated. It will be understood,however, that the total daily usage of the active agent (i.e., compoundsand compositions of the present invention) will be decided by theattending physician within the scope of sound medical judgment. Thespecific effective dose level for any particular subject (i.e., patient)or organism will depend upon a variety of factors including the disorderbeing treated and the severity of the disorder; activity of specificactive agent employed; specific composition employed; age, body weight,general health, sex and diet of the subject; time of administration,route of administration, and rate of excretion of the specific activeagent employed; duration of the treatment; and like factors well knownin the medical arts.

The term “parenteral” as used herein includes subcutaneous, intravenous,intramuscular, intra-articular, intra-synovial, intrasternal,intrathecal, intrahepatic, intralesional and intracranial injection orinfusion techniques.

As used herein, a “therapeutically effective amount” means an amount ofa substance (e.g., a therapeutic agent, composition, and/or formulation)that elicits a desired biological response. In some embodiments, atherapeutically effective amount of a substance is an amount that issufficient, when administered as part of a dosing regimen to a subjectsuffering from or susceptible to a disease, disorder, and/or condition,to treat, diagnose, prevent, and/or delay the onset of the disease,disorder, and/or condition. As will be appreciated by those of ordinaryskill in this art, the effective amount of a substance may varydepending on such factors as the desired biological endpoint, thesubstance to be delivered, the target cell or tissue, etc. For example,the effective amount of a provided compound in a formulation to treat adisease, disorder, and/or condition is the amount that alleviates,ameliorates, relieves, inhibits, prevents, delays onset of, reducesseverity of and/or reduces incidence of one or more symptoms or featuresof the disease, disorder, and/or condition. In some embodiments, a“therapeutically effective amount” is at least a minimal amount of aprovided compound, or composition containing a provided compound, whichis sufficient for treating one or more symptoms of an MK2-mediateddisesase or disorder.

As used herein, the terms “treatment,” “treat,” and “treating” refer topartially or completely alleviating, inhibiting, delaying onset of,preventing, ameliorating and/or relieving a disorder or condition, orone or more symptoms of the disorder or condition, as described herein.In some embodiments, treatment may be administered after one or moresymptoms have developed. In some embodiments, the term “treating”includes preventing or halting the progression of a disease or disorder.In other embodiments, treatment may be administered in the absence ofsymptoms. For example, treatment may be administered to a susceptibleindividual prior to the onset of symptoms (e.g., in light of a historyof symptoms and/or in light of genetic or other susceptibility factors).Treatment may also be continued after symptoms have resolved, forexample to prevent or delay their recurrence. Thus, in some embodiments,the term “treating” includes preventing relapse or recurrence of adisease or disorder.

As used herein, the term “inhibitor” is defined as a compound that bindsto and/or inhibits the target protein kinase, MK2, with measurableaffinity. In certain embodiments, an inhibitor has an IC₅₀ and/orbinding constant of less than about 50 μM, less than about 1 μM, lessthan about 500 nM, less than about 100 nM, or less than about 10 nM.

The terms “measurable affinity” and “measurably inhibit,” as usedherein, means a measurable change in MK2 activity between a samplecomprising a compound of the present invention, or composition thereof,and MK2, and an equivalent sample comprising MK2, in the absence of saidcompound, or composition thereof.

As used herein, the term “irreversible” or “irreversible inhibitor”refers to an inhibitor (i.e. a compound) that is able to be covalentlybonded to a kinase in a substantially non-reversible manner. That is,whereas a reversible inhibitor is able to bind to (but is generallyunable to form a covalent bond with) a kinase, and therefore can becomedissociated from the kinase, an irreversible inhibitor will remainsubstantially bound to a kinase once covalent bond formation hasoccurred. Irreversible inhibitors usually display time dependency,whereby the degree of inhibition increases with the time with which theinhibitor is in contact with the enzyme. In certain embodiments, anirreversible inhibitor will remain substantially bound to a kinase oncecovalent bond formation has occurred and will remain bound for a timeperiod that is longer than the life of the protein.

Methods for identifying if a compound is acting as an irreversibleinhibitor are known to one of ordinary skill in the art. Such methodsinclude, but are not limited to, enzyme kinetic analysis of theinhibition profile of the compound with a kinase, the use of massspectrometry of the protein drug target modified in the presence of theinhibitor compound, discontinuous exposure, also known as “washout,”experiments, and the use of labeling, such as radiolabelled inhibitor,to show covalent modification of the enzyme, as well as other methodsknown to one of skill in the art.

As used herein, the term “drug resistance” refers to changes in thewild-type nucleic acid sequence coding a target protein, and/or theamino acid sequence of the target protein, and/or the amino acidsequence of another protein, which changes decrease or abolish theinhibitory effect of the inhibitor on the target protein. Withoutwishing to be bound by any particular theory, it is believed thatcertain compounds of the present invention, i.e., compounds that areirreversible kinase inhibitors, may be effective inhibitors of drugresistant forms of protein kinases.

3. Description of Examplary Embodiments:

As described herein, the present invention provides irreversibleinhibitors of MK2 kinase. Without wishing to be bound by any particulartheory, it is believed that compounds of the invention comprise a moietycapable of covalently binding to a key cysteine residue in the bindingdomain of MK2 kinase. Such a moiety is referred to herein as a “reactivemoiety.” One of ordinary skill in the art will appreciate that MK2kinase, and mutants thereof, have a cysteine residue in the bindingdomain. Without wishing to be bound by any particular theory, it isbelieved that proximity of a reactive moiety, present on a provided MK2inhibitor, to the cysteine of interest facilitates covalent modificationof that cysteine by the reactive moiety.

The cysteine residues of interest can also be described by anidentifying portion of the amino acid sequence of MK2 kinase whichincludes the cysteine of interest. Thus, in certain embodiments, Cys140of MK2 is characterized in that Cys140 is the cysteine embedded in thefollowing amino acid sequence of MK2:

In certain embodiments, the amount of compound in compositionsof this invention is such that it is effective to measurably inhibitMK2, or a mutant thereof, in a biological sample or in a patient. Incertain embodiments, a composition of this invention is formulated foradministration to a patient in need of such composition. In someembodiments, a composition of this invention is formulated for oraladministration to a patient.

Compounds and compositions, according to method of the presentinvention, are administered using any amount and any route ofadministration effective for treating or lessening the severity of adisorder provided herein (i.e., an MK2-mediated disease or disorder).The exact amount required will vary from subject to subject, dependingon the species, age, and general condition of the subject, the severityof the infection, the particular agent, its mode of administration, andthe like. Compounds of the invention are preferably formulated in unitdosage form for ease of administration and uniformity of dosage.

Compositions of the present invention may be administered orally,parenterally, by inhalation spray, topically, rectally, nasally,buccally, vaginally, intraperitoneally, intracisternallyor via animplanted reservoir. In some embodiments, the compositions areadministered orally, intraperitoneally or intravenously.

Sterile injectable forms of the compositions of this invention may beaqueous or oleaginous suspension. These suspensions may be formulatedaccording to techniques known in the art using suitable dispersing orwetting agents and suspending agents. The sterile injectable preparationmay also be a sterile injectable solution or suspension in a non-toxicparenterally acceptable diluent or solvent, for example as a solution in1,3-butanediol. Among the acceptable vehicles and solvents that may beemployed are water, Ringer's solution and isotonic sodium chloridesolution. In addition, sterile, fixed oils are conventionally employedas a solvent or suspending medium.

For this purpose, any bland fixed oil may be employed includingsynthetic mono- or di-glycerides. Fatty acids, such as oleic acid andits glyceride derivatives are useful in the preparation of injectables,as are natural pharmaceutically-acceptable oils, such as olive oil orcastor oil, especially in their polyoxyethylated versions. These oilsolutions or suspensions may also contain a long-chain alcohol diluentor dispersant, such as carboxymethyl cellulose or similar dispersingagents that are commonly used in the formulation of pharmaceuticallyacceptable dosage forms including emulsions and suspensions. Othercommonly used surfactants, such as Tweens, Spans and other emulsifyingagents or bioavailability enhancers which are commonly used in themanufacture of pharmaceutically acceptable solid, liquid, or otherdosage forms may also be used for the purposes of formulation.

Injectable formulations can be sterilized, for example, by filtrationthrough a bacterial-retaining filter, or by incorporating sterilizingagents in the form of sterile solid compositions which can be dissolvedor dispersed in sterile water or other sterile injectable medium priorto use.

In order to prolong the effect of a compound of the present invention,it is often desirable to slow the absorption of the compound fromsubcutaneous or intramuscular injection. This may be accomplished by theuse of a liquid suspension of crystalline or amorphous material withpoor water solubility. The rate of absorption of the compound thendepends upon its rate of dissolution that, in turn, may depend uponcrystal size and crystalline form. Alternatively, delayed absorption ofa parenterally administered compound form is accomplished by dissolvingor suspending the compound in an oil vehicle. Injectable depot forms aremade by forming microencapsule matrices of the compound in biodegradablepolymers such as polylactide-polyglycolide. Depending upon the ratio ofcompound to polymer and the nature of the particular polymer employed,the rate of compound release can be controlled. Examples of otherbiodegradable polymers include poly(orthoesters) and poly(anhydrides).Depot injectable formulations are also prepared by entrapping thecompound in liposomes or microemulsions that are compatible with bodytissues.

In some embodiments, provided pharmaceutically acceptable compositionsare formulated for oral administration. Such formulations may beadministered with or without food. In some embodiments, pharmaceuticallyacceptable compositions of this invention are administered without food.In other embodiments, pharmaceutically acceptable compositions of thisinvention are administered with food. Pharmaceutically acceptablecompositions of this invention may be orally administered in any orallyacceptable dosage form including, but not limited to, capsules, tablets,aqueous suspensions or solutions. In the case of tablets for oral use,carriers commonly used include lactose and corn starch. Lubricatingagents, such as magnesium stearate, are also typically added. For oraladministration in a capsule form, useful diluents include lactose anddried cornstarch. When aqueous suspensions are required for oral use,the active ingredient is combined with emulsifying and suspendingagents.

MK2 Kinase

MAP kinase-activated protein kinase 2 (“MK2”) is an enzyme that inhumans is encoded by the MAPKAPK2 gene. This gene encodes a member ofthe Ser/Thr protein kinase family. This kinase is regulated throughdirect phosphorylation by p38 MAP kinase. In conjunction with p38 MAPkinase, this kinase is known to be involved in many cellular processesincluding stress and inflammatory responses, nuclear export, geneexpression regulation and cell proliferation. Heat shock protein HSP27was shown to be one of the substrates of this kinase in vivo. Twotranscript variants encoding two different isoforms have been found forthis gene.

MK2 is a multi-domain protein consisting of an N-terminal proline-richdomain, a catalytic domain, an autoinhibitory domain and at theC-terminus a nuclear export signal (NES) and nuclear localization signal(NLS). Two isoforms of human MK2 have been characterized. One isoformconsists of 400 amino acids and the other isoform 370 residues which isthought to be a splice variant missing the C-terminal NLS. MK2 islocated in the nucleus of the cell and upon binding and phosphorylationby p38, the MK2 NES becomes functional and both kinases areco-transported out of the nucleus to the cytoplasm. Interestingly,transport of the MK2/p38 complex does not require catalytically activeMK2, as the active site mutant, Asp207Ala, is still transported to thecytoplasm. Phosphorylation of human MK2 by p38 on residues T222, S272and T334 is thought to activate the enzyme by inducing a conformationalchange of the autoinhibitory domain thus exposing the active site forsubstrate binding. Mutations of two autoinhibitory domain residues W332Aand K326E in murine MK2 demonstrate an increase in basal activity and aC-terminal deletion of the autoinhibitory domain renders the enzymeconstitutively active, providing additional evidence to the role of thisdomain in inhibition of MK2 activity.

Mitogen-Activated Protein Kinase-Activated Protein Kinase 2 Omnia® Assayfor Compound Potency Assessment:

The protocol below describes a continuous-read kinase assay optimized tomeasure potency of compounds against p38α activated, mitogen-activatedprotein kinase-activated protein kinase 2 (MAPKAP-K2 or MK2) enzyme.Further details of this assay are described by Life Technologies,Carlsbad, Calif. on their website at the following URL:http://tools.lifetechnologies.com/content/sfs/manuals/omnia_kinase_assay_man.pdf.

[Reagent] used:

[MK-2]=0.4 nM,

[ATP]=10 μM and

[ST3-Sox]=10 μM (ATP ^(app)K_(M)=10 μM)

Briefly, 10× stock solutions of MK2 (PV3317, from Life Technologies),1.13×ATP (AS001A), and Sox conjugated peptide substrate, S/T3-Sox,(KZN1031) were prepared in IX kinase reaction buffer consisting of 20 mMTris, pH 7.5, 5 mM MgCl₂, 1 mM EGTA, 5 mM A-glycerophosphate, 5%glycerol (10× stock, KB001A) and 0.2 mM DTT (DS001A). Enzyme solution (5μL) was added to each of DMSO (5 μL) or serially diluted test compoundsprepared in DMSO in a Corning (#3574) 384-well, white, non-bindingsurface microtiter plate (Corning, N.Y.). Kinase reactions were startedwith the addition of 45 μL of the ATP-peptide substrate S/T3-Sox mix andmonitored every 71 seconds for 120 minutes at ×_(ex)360/λ_(em)485 in aSynergy H4 plate reader from BioTek (Winooski, Vt.) at room temperature.

Background signals from the no enzyme control wells were subtracted fromall progress curves. The initial linear portions of the net progresscurves were fit according to a linear equation to yield the slope andpercentage of inhibition (% inhibition) at each compound concentration.The net progress curves obtained during the first two hours of reactionswere also fit according to an ascending single-exponential equation(Eq. 1) to yield k_(obs) values at each compound concentration. Plots of% Inhibition versus inhibitor concentrations were fit according to adose-response equation (Eq. 2) to generate IC₅₀ and Hill slope valueswhile plots of k_(obs) versus inhibitor concentration were fit accordingto Equation 3 (Eq. 3) to generate apparent k_(inact)/K₁ values using theGraphPad PRISM software (Version 6.00; GraphPad San Diego, Calif.).

$\begin{matrix}{F = {V_{0}\frac{\left( {1 - e^{{- k_{obs}}t}} \right)}{k_{obs}}}} & \left( {{Eq}.1} \right)\end{matrix}$where F is the fluorescence intensity from the plate reader, V₀ is aconstant reflecting the relationship between the instrument readout andproduct concentration, t is time, e is Euler's number, and k_(obs) isthe observed inactivation rate constant.

$\begin{matrix}{{\%{Inhibition}} = \frac{100}{1 + \left( \frac{{IC}_{50}}{\lbrack I\rbrack} \right)^{n}}} & \left( {{Eq}.2} \right)\end{matrix}$where % Inhibition is percentage of inhibition, IC₅₀ is half maximalinhibitory concentration, [I] is the inhibitor concentration, and n isthe Hill slope.

$\begin{matrix}{k_{ops} = {\frac{k_{inact}}{K_{1}}\frac{\lbrack I\rbrack}{2}}} & \left( {{Eq}.3} \right)\end{matrix}$where k_(obs) is the observed inactivation rate constant, k_(inact) isthe apparent inactivation rate constant, K₁ is the apparent inhibitionconstant, and [I] is the inhibitor concentration. Results from thisassay, showing IC₅₀ (i.e. the concentration at which a test compoundinhibits substrate peptide phosphorylation 50%) are reported innanomolar. Potency results for the compounds tested are shown in Table Ain the column entitled “MK2 IC₅₀.”

Mass Spectrometry Assay for Detecting Level of Covalent Modification ofMK2

Compounds I-1 through I-50 of the invention were assayed in a massspectrometric assay to measure their ability to covalently modify MK2protein. The procedure for this assay follows. Intact MK2 protein(Invitrogen, Cat. No. PRS320A) was incubated for 60 minutes at roomtemperature with a 10-fold excess of test compound to protein. Aliquotsof the resulting mixture (6 μL each) were diluted with 0.2%trifluoroacetic acid (TFA, 10 μL) prior to micro C4 ZipTipping directlyonto the MALDI target using sinapinic acid as the desorption matrix (10mg/ml in 0.1% TFA:acetonitrile 50:50, v/v). The centroid mass of thetarget protein in the control sample was compared with the centroid massof the target protein incubated with compound. A shift in the centroidmass of the treated protein compared to the untreated protein wasdivided by the molecular weight of the compound. This number correspondsto the percentage of modified protein (a measure of the proportion oftotal target protein covalently bound to the test compound) after onehour incubation. Results from this assay are reported in Table A underthe column “Mass Modification”.

Compounds I-51 through I-129 were assayed in a magnetic bead massspectrometric assay to measure their ability to covalently modify MK2protein. The procedure for this assay follows. MK2 protein (Invitrogen,Cat. No. PR5320A) was incubated for 60 minutes at room temperature witha 10-fold excess of test compound to protein. 3 μL of magnetic Ni-NTAbeads were added to the 6 μL aliquots of sample, washed, eluted with0.2% trifluoroacetic acid (TFA, 2 μL), and spotted directly onto theMALDI target using sinapinic acid as the desorption matrix (10 mg/ml in0.1% TFA:acetonitrile 50:50, v/v). The centroid mass of the targetprotein in the control sample was compared with the centroid mass of thetarget protein incubated with compound. A shift in the centroid mass ofthe treated protein compared to the untreated protein was divided by themolecular weight of the compound. This number corresponds to thepercentage of modified protein (a measure of the proportion of totaltarget protein covalently bound to the test compound) after one hourincubation. Results from this assay are reported in Table A under thecolumn “Mass Modification”.

MK2 Cellular Assay—Detection of Total and Phospho-Hsp27 (Serine 78) byMSD ELISA (Thp1)

Compounds of the invention were assayed in Thp-1 human acute monocyticleukemia cells to measure inhibition of MK2 activity. Thp-1 cells weregrown in culture medium containing RPMI/10% FBS (fetal bovineserum)/0.05 mM 2-mercaptoethanol. 72 hours prior to the assay, 8×10⁴cells per well were plated in a 96 well flat bottom plate along with 10ng/mL phorbol 12-myristate 13-acetate (PMA). Cells were cultured in anincubator at 37° C. until needed for the assay. Cell plate media wasreplaced with culture media just prior to assay while compound dilutionswere being made.

Stock solutions of test compound, 1 mM in DMSO, were prepared. 0.9 μl oftest compound was added to 300 μl cell media for a startingconcentration of 3000 nM. Three-fold serial dilutions (1:3) were made incell assay media until the final concentration of 0.15 nM. Cell platemedia was discarded, followed by addition of 100 μl of the compoundcontaining media. The resulting preparation was incubated at 37° C. for1 hour.

Test compound-containing cell assay media was removed and the cells werewashed once with cell assay media. Cell assay media containing 50 ng/mLLPS (lipopolysaccharide) was added to the each well and incubated for 45minutes. Following LPS incubation, the cells were washed once with PBS(phosphate-buffered saline) and lysed with 60 μl Cell Extraction Buffer(Invitrogen #FNN0011) plus protease and phosphatase inhibitors. Theplate was then stored at −80° C. until further analysis.

The MULTI-SPOT Phospho(Ser78)/Total HSP27 ELISA Assay kit was purchasedfrom Meso Scale Delivery (MSD; catalog #K15128D). MSD provides a platethat has been pre-coated with capture antibodies for phosphor-HSP27(Ser78) and total HSP27. The pre-coated MSD plate was blocked with 150μL/well of 3% BSA in MSD wash buffer. The preparation was placed on ashaker at room temperature for an hour. While the ELISA plate wasblocked, the cell assay plate stored at −80° C. was placed on a shakerat 4° C. for 1 hour to thaw.

The blocked MSD plate was washed on a plate washer, tapping out the lastbit of wash solution, followed by addition of 30 μl of the lysate fromthe cell assay plate. The preparation was covered and incubated for 1hour at room temperature. The lysate was removed, the plate was washed 3times on a plate washer and the last bit of wash buffer was tapped outand replaced with 25 μl/well detection antibody (anti-total HSP27conjugated with an electrochemiluminescent compound, MSD SULFO-TAGlabel, supplied in kit) made in 1% BSA/MSD wash buffer. The plate wasincubated for 1 hour at room temperature on a shaker, followed by 3washes. The last bit of wash buffer was tapped out. 150 μl/well 1×MSDread buffer was added (4× read buffer supplied with kit) and the platewas analyzed on the MSD SECTOR®Imager for analysis. The SECTOR®Imagermeasures intensity of emitted light to provide a quantitative measure ofphosphorylated HSP27 (Ser78) and total HSP27 present in the sample. Therelative percent phosphoprotein in a sample is calculated by dividingthe Phospho-HSP27 signal intensity over the total HSP27 signal intensitymeasured in each well. A curve fitting analysis was performed usingGraph Pad Prism software to generate an EC₅₀ based on the inhibitoryresponses of the LPS-induced p-HSP27/total HSP27 signal ratio'snormalized to DMSO-treated controls (set at 100% signal intensity).Results from this assay, showing EC₅₀ (i.e. the concentration at which atest compound inhibits phosphorylation of Hsp27 by 50%) are reported innanomolar. Results from this assay are reported in Table A under thecolumn “pHSP27 signaling ECs.”
